   Wenn nun durch diese Arbeitsweise der volumetrische Wirkungsgrad der Pumpe eine geringe Verminderung erfährt, so erreicht man doch dadurch derartige, das Wesen der Erfindung darstellende Vorteile, die für eine brauchbare und einwandfreie   Heisswasserpumpe   unerlässlich sind.

   If the volumetric efficiency of the pump undergoes a slight reduction as a result of this mode of operation, then such advantages, which represent the essence of the invention and are essential for a usable and faultless hot water pump, are achieved. The relief of the suction chamber is complete, the piston needs to move backwards

   which causes great difficulties when pumping hot water, especially at temperatures above 100. The attachment of the stuffing box G also makes the Liderung on the front side of the piston dispensable, which would otherwise be necessary to go forward during the

 Fig. 3 shows the working diagram of the front cylinder chamber (pressure chamber).

Claims (1)

PATENT-ANSPRUCH: Pumpe zur Förderung heisser Flüssigkeiten. dadurch gekennzeichnet, dass unter Vermeidung von Saugventilen und unter Anwendung von Saugöffnungen zur Entlastung des Saugraumes der Pumpenhub nach Freigabe der Saugöffnungen noch so weit vergrössert wird, dass das hiedurch entstandene Volumen gleich oder grösser als das in der hinteren Totpunktlage vollständig in den Pumpenraum eingetauchte Kolbenstangenvolumen ist. wodurch trotz der verschiedenenwirksamenQuerschnittsflächenderbeidenKolbenseitendiegefördertenFlüssigkeits- EMI2.4 auf die Druckseite des Kolbens die zur Entlastung des Saugraumes zu vermeidende Drucksteigerung nicht eintritt. PATENT CLAIM: Pump for pumping hot liquids. characterized in that while avoiding suction valves and using suction openings to relieve the suction chamber, the pump stroke is increased after the suction openings have been released so that the resulting volume is equal to or greater than the piston rod volume completely immersed in the pump chamber in the rear dead center position . whereby, despite the different effective cross-sectional areas of the two piston sides, the EMI2.4 on the pressure side of the piston, the pressure increase to be avoided to relieve the suction chamber does not occur.
